Sodium lactate is widely used in the food industry as a preservative and pH regulator. It helps extend the shelf life of products like meat, poultry, and baked goods by inhibiting the growth of bacteria. In cosmetics and personal care products, it acts as a humectant, retaining moisture in the skin and improving hydration. It is also used in medical settings as part of intravenous solutions to treat dehydration or electrolyte imbalances. Additionally, sodium lactate serves as a buffering agent in various industrial processes to maintain stable pH levels. Its versatility makes it valuable across multiple sectors.
